ADJUSTABLE cm.

Application filed December 7, 1923. Serial No. 679,279.

To all whom it may concern:

Be it known that I, Nrorroms MARCALUS, a citizen of the United States, residin at Plainfield, in the county of Union and tate of New Jerse and useful mprovements in Ad us table Gibs, of which the following is a specification.

This invention relates to means for accurately connecting two relatively movable parts, such as a planer table and its bed as shown in the. accompanying drawing. A gib is ordinarily employed to retain the movable member in its proper working 081- tion on the bed or other member. narily this gib is secured to one member and adjusted smooth sliding frictionless engagement w1th the other member. Since these engaging surfaces are usually in a remote and inaccessible place, it is impossible to secure the accurate sliding fit desired and the engagement istherefore usually too loose or too tight. The primary object of my invention is to provide certain of the cooperating portions of the gib and its retaining member withone or more recesses throughwhich' access may be had, with a gage or OthBIWlSQ, to the coo crating surfaces of the gib and other mem er.

As shown in the drawing, the recess or recesses can be formed either in the gib or in the gib retaining member. I preferably form the recesses in the gib. Another object of my invention is to provide a flat platelike holdin gib having a gage receiving recess forme therein and extending only partiall across the holding face of the gib.

With the above and other objects in view, my invention consists in the features of construction and operation set forth in the following specification and illustrated in the accompanying drawing. In such drawing annexed hereto and forming a part of this specification, I have illustrated certain embodiments of my invention in connection with a planer but it will be understood that the invention can be otherwise embodied and that the drawing is not to be construed as defining or limiting the scope of the invention, the claims appended to this specifica; tion being relied upon for that purpose.

Referring to the figures of the drawing: Figure 1 is .a fragmentary side elevation have invented certain new rdias accurately as possible to have'av of a planer bed having a planer table slidably mounted thereon and secured by my improved gib.

F 1g 2 is a fragmentary sectional view thereof on line 2+2 of Fig. 1.

Fig. 3 is a plan view of my improved gib, this view being taken on line 33 of Fig. 1. Fig. 4 is a fragmentary side elevation of a modified form of my invention.

' Fig. 5 is a fragmentary sectional view thereof taken on line 55 of Fig. 4.

Referring more specifically to the drawing by reference characters, 1 indicates a planer bed on which a planer table 2 is slldably mounted, one of the table guideways being shown at 3. Thetable is connected to the bed'to prevent chattering and looseness by means of a plurality'of gibs secured to the table and extending over "and beneath a portion of the bed. Each 'gib comprises substantially a flat oblong plate bolted directly to the table; y

In Figs. 1, 2 and 3,. the gib 4 comprises a flat oblong plate having'a face or side 5 adapted to be secured to the downwardly pro ect1ng portion 6 of the table and to extend over and beneath a shoulder 7 of the bed 1. The gib is secured to the table by means of bolts 8 extending upwardly through the gib and screw threaded into the table portion 6. The function of thegibs is; to hold the table against chatter and looseness when reciprocating on the bed. T0 properly perform' this function, the gibs must have a very fine and accurate engagement with the shoulder 7 of the bed.

Each ib 4 is provided with two 9 exten ing partially across each face 5 thereof. As will be noted, the recesses are formed in the portion of the gib which engages the member 6, thus leavin the shoulder-engaging portion intact. en applymg the gib or when adjustment thereof is necessary, the recesses provide access to the cooperating engaging surfaces of the gib and shoulder 7. The operator can therefor observe the relation of these parts through the recesses and can use a knife gage or other instrument in determining the proper and accurate adjustment of the gib. In this manner, the gib can be so accurately adjusted that a smooth sliding-frictionless engagement of the gib with thehed is obtained. t will of course be understood slightly that the gib can be adjusted in various ways, as for example by providing shims between the gib. and the portion 6 of the table.

In Figs. 4 and5, I have illustrated a modified form of my invention in which the observation recesses are provided in the-portion 6 of the table instead of in the gib. In this form of the invention, the gib 10 is a'continuous oblong plate secured to the portion 6 of the table by the bolts 8. Recesses 11 are formed in the portion 6 of the table directly adjacent the upper working fac of the gib. The recesses 11 provide access to the engaging surfaces of the gib and shoulder in the same manner as-above described in reference to the receses 9 of the What I claim is: i

1. A- holding gib having recess formed therein.

2. A flat plate-like holding gib having a gage receiving recess formed therein and extending only partially across the holding face of the 'b. i u

3. A hold i iiggib 'for securingtivomembers together, the gib having one portion adapted to secured ,against on -0f the members and an adjacent portion adapted to engage the other member and the first said portion being recessed cess to the member-engaging part of the other portion. 4. A flat plate-like holding gib for securing two members together, one face of the gib being adaptedto be secured against one of the members a gage receiving securing a port, one side of the gib being adapted to be secured against the reciprocatory mem. her and to extend over the support, and a portion of the gibadjacent the said side being to provide ac' and to extend over the other I, member, and a portion of the gib adjacent the recessed to provide access to the surface extending over the support.

6. An oblong plate-like holding gib for securing a riciprocatory member to its sup port, one side of the gib being adapted to be secured against the reciprocatnry member and to extend over the support, and portions of the gib adjacent the said side being recessed at a plurality of laces to rovide access to the surface extending over e sup- )ort.

I 7. In combination, a member, a member movable thereon, and a gib secured to one member and extending over the other member, certain of the cooperatin portions of the gib and the said one membeingrecesed to rovide access to the cooperating ortions o the giband the said other memer.

8. In combination, a member, a member movable thereon, and a gib secured to the movable member and extending over the other member, certain of the cooperating portions of the gib and movable member being recessed to provide access to the cooperating portions of the gib and the said other member.

9. In combination, a member, a member lineally movable thereon, and an oblong plate-like gib secured to one member and extending over the other member, certain of the cooperatin portions of the gib and the said one mem 1' being recessed to provide access to the cooperating rtions of the gib and the said other mem r.

In ccmbination, a su port. a table slidably mounted thereon, and a gib secured to the table and extendin over a shoulder on the su port, the side 0 the gib adjacent the table ing recessed to provide access to the cooperating surfaces of the gib and shoulder. I

In testimony whereof, I hereto aflix my signature.

NICHOLAS MAROALUS.
